Answer:
10
Step-by-step explanation:
19 divided by 19 is equal to 1 so you cross out 19 and are left with "b".
190 divided by 19 is equal to 10.
b=10
Answer:
y4.5
Step-by-step explanation:
The value of the square root of 140 lies between 11 and 12. The square root of 140 is 11.83
Step-by-step explanation:
The x-intercept is at (-3, 0). To find the slope of the perpendicular line, let's rewrite the equation to its slope-intercept form, which is
y = (2/3)x + 2
This means that the perpendicular line has a slope m = -3/2. So the slope-intercept form of this new line is
y = -(3/2)x + k. Since this line passes through (-3, 0), we cal solve for k:
0 = -(3/2)(-3) + k or k = -9/2
So our equation becomes (slope-intercept form)

or in its standard form,
